<p><a class="link" href="GtkScrollable.html" title="GtkScrollable"><span class="type">GtkScrollable</span></a> is an interface that is implemented by widgets with native
scrolling ability.</p>
<p>To implement this interface you should override the
<a class="link" href="GtkScrollable.html#GtkScrollable--hadjustment" title="The “hadjustment” property"><span class="type">“hadjustment”</span></a> and <a class="link" href="GtkScrollable.html#GtkScrollable--vadjustment" title="The “vadjustment” property"><span class="type">“vadjustment”</span></a> properties.</p>
<div class="refsect3">
<a name="id-1.3.16.4.10.4"></a><h4>Creating a scrollable widget</h4>
<p>All scrollable widgets should do the following.</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>When a parent widget sets the scrollable child widget’s adjustments,
the widget should populate the adjustments’
<a class="link" href="GtkAdjustment.html#GtkAdjustment--lower" title="The “lower” property"><span class="type">“lower”</span></a>, <a class="link" href="GtkAdjustment.html#GtkAdjustment--upper" title="The “upper” property"><span class="type">“upper”</span></a>,
<a class="link" href="GtkAdjustment.html#GtkAdjustment--step-increment" title="The “step-increment” property"><span class="type">“step-increment”</span></a>, <a class="link" href="GtkAdjustment.html#GtkAdjustment--page-increment" title="The “page-increment” property"><span class="type">“page-increment”</span></a> and
<a class="link" href="GtkAdjustment.html#GtkAdjustment--page-size" title="The “page-size” property"><span class="type">“page-size”</span></a> properties and connect to the
<a class="link" href="GtkAdjustment.html#GtkAdjustment-value-changed" title="The “value-changed” signal"><span class="type">“value-changed”</span></a> signal.</p></li>
<li class="listitem"><p>Because its preferred size is the size for a fully expanded widget,
the scrollable widget must be able to cope with underallocations.
This means that it must accept any value passed to its
<a class="link" href="GtkWidget.html#GtkWidgetClass.size-allocate"><code class="function">GtkWidgetClass.size_allocate()</code></a> function.</p></li>
<li class="listitem"><p>When the parent allocates space to the scrollable child widget,
the widget should update the adjustments’ properties with new values.</p></li>
<li class="listitem"><p>When any of the adjustments emits the <a class="link" href="GtkAdjustment.html#GtkAdjustment-value-changed" title="The “value-changed” signal"><span class="type">“value-changed”</span></a> signal,
the scrollable widget should scroll its contents.</p></li>
